Specification of Letters Patent.

Application le June 3.9, 1913.. Serial No. 632,415.

To aZZ LU/LomiA it may eminem Be it known that CHARLES A. LIND- STRM, a citizen of the United States, residing at No. 138 Stratford avenue, Pittsburgh,

E. E., in the county of Allegheny and Sta a of Pennsylvania, have invented certain new and useful Improvements in Car Side (jenstruction, of which the following is a specification,

An object of the present invention is to provide an improve/l form of door and side construction for that type of bottom dump car generally known as an ore car, such as that described in my pending applical5 tions for United States patents, Serial Nos.

563,479 and 599,507, in which the lading is.

discharged through the car bottom.

The tendencyv of ore to arch or bridge over the discharge opening in the bottom ot' the car has alreadui1 been referred to in my pending applications aoove referred to, and it has been found in practice that this tendency of the lading to bridge or arch, causes a portion ot' the ore to stick or lodge in the angular portion of the drop door illustrated in the li'\vings of said applications. The

the central portion ot amount of ore which sticks in the annular.

portion of the door varies according to the Vnatural character of the orc itself, and nccordingr 'to the quantity oi n'loisture contained in the ore, which together with the jolting and jarring inlieient in transportation of ore in railway cars, increases the tendency oi the ore to stick and cake, and as a result of which special means have to oe used to dislodge such ore trom the drop door when the major poimon of the ore contained in the car has been damped,

40 it will be readily understood, from an inspection 0I" Figure 2 of the drawings, that the advantage of the i. form of doors shown therein, resides in the fact that during the opening movement ofthe doors, the Whole of the lower inclined rportion of the doors movesdownwardly away from the load t an extent which is greatest at the edges of the doors nearest to the longitudinal center line of the cewv and decreasing somewhat to Ward the angela? portions of the doors ne est the vertical piane car tl sult of Snch movement of the doors o that the support a'orded to the lading by' u it.

the doors cntirel removed when the doors are opened, this permitting :tree discharge of the lading'. y
